 Obiettivo del progetto (Objective)

'The design of more powerful, fuel-efficient, and environmentally friendly propulsion systems is currently one of the main goals of engine researchers and manufacturers worldwide. State-of-the-art Computational Fluid Dynamics (CFD) methods can be a valuable tool to gain insight into in-cylinder mixing and combustion phenomena, and investigate injection strategies capable of minimizing harmful pollutants from internal combustion engines. The proposed research consists of model development and detailed computational studies of internal combustion engine aerothermochemistry, using state-of-the-art techniques. Emphasis will be placed on large marine diesel engine applications. These studies will be also supported by advanced experiments, performed in parallel by colleagues of the researcher in a number of research institutions worldwide. Specifically, the following four areas will be studied in the course of the proposed research: 1. Modelling of fuel spray atomisation in large marine diesel engines: due to the large size of injectors in marine applications, the governing physics of spray breakup is affected, and thus primary atomisation is characterised by different mechanisms, in comparison with automotive applications. Here, we propose the necessary model development and validation to account for the different physics of spray breakup. 2. Modelling of fuel evaporation: existing evaporation models will be further developed to account for multi-component fuels, as well as to include more realistic drop shapes. 3. Heat transfer modelling: engine heat transfer modelling often mistreats thermal radiation, which can account for up to 50% of the total heat losses. Here, we propose advanced modelling of thermal radiation, as well as a revisit of the assumptions used in convective heat transfer modelling. 4.Application of the tools developed to the modelling of simultaneous injection of fuel and water, for engine emissions reduction without compromising fuel economy.'
